/MADRID, SPAIN, August 3, 2026, 10:30 CEST, RENEWABLE MARKET WATCH™/ Sonnedix, a leading global renewable energy platform with 12 GW of total capacity, has successfully secured a €730 million financing package to support the refinancing, operational optimisation, and new asset construction across its strategic markets in France, Italy, Portugal, and Spain. This milestone transaction underscores Sonnedix’s robust growth trajectory in Europe and highlights the company’s strong track record of trusted partnerships and financial credibility within the sector.
The capital will be strategically deployed across a diversified portfolio of assets in all four countries, including photovoltaic (PV) plants with a combined capacity of approximately 540 MW and two battery energy storage system (BESS) projects. Italy represents the largest market allocation, accounting for over 350 MW of new and optimised capacity, reinforcing Sonnedix’s market leadership in Southern Europe. Through this refinancing, Sonnedix has strengthened its financial platform to accelerate the execution of its hybridisation strategy—integrating advanced storage solutions alongside solar PV—while expanding its customer base and unlocking new revenue streams across core markets.
The financing consortium includes prominent international financial institutions—AIB, CACIB, CIBC, ING, Intesa Sanpaolo, Sabadell, Santander CIB, Societe Generale, and UniCredit—demonstrating broad-based lender confidence in Sonnedix’s business model and growth outlook.
This transaction further accelerates Sonnedix’s momentum across Southern Europe, cementing its leadership in integrating battery storage and hybrid renewable energy systems. By supporting the company’s broader hybridisation strategy, the financing enhances the operational flexibility, resilience, and long-term value creation of Sonnedix’s renewable energy platform.
Axel Thiemann, CEO of Sonnedix, said: “This financing reflects Sonnedix’s commitment to developing high-quality renewable projects in our strategic markets. It follows our recent BESS portfolio acquisition in Italy, and underscores the pace at which we are scaling our storage capabilities across Europe.”
Miguel A. García Mascuñán, CFO of Sonnedix, said: “A €730 million financing is a major milestone for Sonnedix, offering significant financial flexibility and capacity to accelerate our development pipeline across core markets. This also reflects the continued trust and confidence of our partners, and we are proud to continue building on these relationships.”
